Wireless Network Modded To See Through Walls

KentuckyFC writes "The way radio signals vary in a wireless network can reveal the movement of people behind closed doors, say researchers who have developed a technique called variance-based radio tomographic imaging which processes wireless signals to peer through walls. They've tested the idea with a 34-node wireless network using the IEEE 802.15.4 wireless protocol (the personal area network protocol employed by home automation services such as ZigBee). The researchers say that such a network could be easily distributed by the police or military wanting to determine what's going on inside a building. But such a network, which uses cheap off-the-shelf components, might also be easily deployed by your neighbor or anybody else wanting to monitor movements in your home."

There must be a lot of lame parents that do the super silent wiggle. Even when trying to be quiet my wife and I are loud enough that my 17 year old turns up the stereo at the other end of the house.

Granted most people are dysfunctional and believe that Sex=Icky and there fore lead a very sad life.

back when I was in college, everyone knew, if the windows were open you could hear us for miles on a summer night...

You haven lived life if you have not had wild romper set with a screamer..
